Explosion A plane strain model of a high explosive detonation in water is investigated with different meshes and the ALE method. Underwater A This is a plane strain model of a high explosive detonation in water. File underwater_A.k is Lagrangian with a coarse mesh. Underwater B This is a plane strain model of a high explosive detonation in water. File underwater_B.k is Lagrangian with a fine mesh. Underwater C This is a plane strain model of a high explosive detonation in water. File underwater_C.k is Eulerian with 1st order advection and a coarse mesh. Underwater D This is a plane strain model of a high explosive detonation in water. File underwater_D.k is Eulerian with 1st order advection and a fine mesh. Underwater E This is a plane strain model of a high explosive detonation in water. File underwater_E.k is Eulerian with 2nd order advection and a coarse mesh. Underwater F This is a plane strain model of a high explosive detonation in water. File underwater_F.k is Eulerian with 2nd order advection and a fine mesh.
